Chinese scientists set world record with magnetic field 700,000 times stronger than Earth’s

Scientists in China have achieved a new world record by generating a steady magnetic field of 351,000 gauss (35.1 tesla) using a fully superconducting magnet, surpassing the previous global benchmark of 323,500 gauss. This is reported by
China Daily, a partner of TV BRICS.

Researchers report that the advance provides a crucial foundation for fusion energy development, where superconducting magnets are used to form “magnetic cages” that confine plasma at extreme temperatures. Experts claimed that beyond fusion, and next-generation scientific instruments.

The breakthrough was made possible by innovations in high- and low-temperature superconducting coil design, which addressed long-standing technical challenges, including stress concentration and multi-field coupling effects under extreme operating conditions.

Scientists highlight that the result also reflects China’s progress in localising superconducting technologies and materials, strengthening its role in global research on advanced energy systems. As part of international collaborations in plasma physics and experimental fusion, the new record reinforces efforts to accelerate the safe and sustainable use of high-field superconducting magnets worldwide.
